I have got an area chart with a series value which is a field in my dataset.

The legend for the chart is set to show the label of the series plus the label field of the value, seperated by a dash line, in the form of Group1 - Value1.

What I want is to only show the series label in the legend - only show Group1 - but if I leave the label field of the value empty, Nevron component still shows the dash (it shows Group1 - ) Is there a way around the issue?
